ROLLER. SIDE BEARING.

Application led March 1, 1916.

To zZZ whom it may concern:

Be it known that I. JOI-IN F. CConnon, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a. certain new and useful Improvement in Roller Side Bearings,of which the following is a full, clear, concise, and exact description,reference being had to the accompanying drawings, forming a part of thisspecification.

This invention relates to improvements in roller side bearings.

The object of the invention is to provide a roller Side bea ring, moreparticularly adapted for use on railroad cars, and which is composed offew parts simply arranged, which may be cheaply manufactured, easilyapplied and repaired, which permits of a wide range of travel. which isself centering and also anti-rattling.

In the drawing forming a part of this specification, Figure 1 is anelevational view of portions of two holsters of a railway car, showingmy improvements in connection therewith. Fig. 2 is a top plan view ofthe truck bolster showing my roller side bearing applied thereon. AndFigs. 3 and 4 are enlarged sectional views taken respectively on thelines 3-3 of Fig. 2 and elf-4 of Fig. 3.

In said drawing, 10 denotes a truck bolster and 11 a body bolsterswiveled at the center in the usual manner. The body bolster is providedwith a striking plate 12, and the truck bolster has my improved rollerside bearin A applied thereto.

As shown in the drawing, the improved side bearing A comprises a castingB, roller C and spring axle D. rIhe casting B has a bottom plate 13,outer vertical wall 14 and end limiting walls 15*15. The wall 14, at thecenter thereof, is provided with an enlargement 1G having alongitudinally extending slot 17 therein, said slot 17 having extendingtherein the end 18 of the spring rod axle D. For increased durability,the casting B is provided with a hardened insert plate 19 on which theroller C bears when in operation.

rlhe spring axle D is preferably formed Speccation of Letters Patent.

from a rod of spring steel having an axle portion proper 20, shoulderedvertically ex tending portion 21 and horizontal arm 22, the latter atits inner end being Hattencd as indicated at and riveted to the truckbolster. The spring axle 22 is preferably so bent, as indicated by thedotted lines in Fig. 1, that when it is riveted to the truck bolster,the roller C will be normally held out of engagement with the wear plate19, thereby minimizing tendency of the roller to rattle. In operation,as the ends of the bolsters approach each other, the roller C will beforced down on its bearing plate 19 and will then roll in accordancewith the relative movement between the holsters. The limit of movementof the roller is determined by the end walls 15-15 of the asting ll andit is obvious that upon separation of the bolsters, the roller C willautomatically be returned to central normal position due to the inherentelasticity in the rod l).

From the preceding description, it will be seen that the roller bearingwhich I have provided is extremely simple, consists of few parts, thespring rod axle may be easily and cheaply renewed and furthermore. theroller C may be made substantially solid. an iinportant consideration indevices of this class where the pressure often becomes very lgreat.

As shown, the roller C need only7 be cored or recessed to receive therelatively small diameter axle rod. It is also apparent that the rollerC is permitted suthcient play inwardly and outwardly relatively to thecenter of the trucks to accommodate itself to the proper positions whilebeing actuated, the wall 1t limiting the outward movement of the rollerC and the shouldered portion 21 of the rod limiting its inward movement.

I claim:

1. In a roller side bearing, the combination with a bolster. of aroller, a spring axle on which said roller is mounted, the latter beingso formed as to normally support said roller out of engagement with anypart of the bolster.

2. In a roller side bearing, the combination with a bolster, a castingsecured to said bolster, and an anti-friction roller bodily moyablymounted in said casting, of a spring ed on Jthe free end of said rod andnormally rod axle on which said rollei1 is mounted, supported thereby.

said rod axle having` its inner end rigidly 1n Witness that I claim theforegoing I secured to the bolster and provided interhave hereuntosubscribed my name this 28th l0 mediate its ends with a bent section toform day of Feb., 1916.
